Its ceramic dielectric construction allows for compact size and high capacitance values, making it indispensable in modern electronics, particularly where space is at a premium and environmental robustness is critical.

Key Specifications

• Apps. (Automotive Grade): This attribute signifies that the capacitor is specifically engineered and tested to meet the rigorous demands of automotive electronics. Components designated as “Automotive Grade” must withstand extreme temperatures, vibrations, and electrical stresses common in vehicles, ensuring long-term reliability and safety.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality passive components, including capacitors, inductors, and ferrites. Their brand signifies a commitment to innovation, reliability, and precision engineering in the electronics industry.
• Feature (AEC-Q200 Mid150°C): This feature highlights compliance with AEC-Q200, a critical stress test qualification standard for passive electronic components used in automotive applications. The “Mid150°C” indicates its capability to operate reliably at an elevated maximum operating temperature of 150°C, crucial for under-the-hood or high-power applications.
• AEC-Q200 (YES): Explicitly confirms that this MLCC meets the stringent AEC-Q200 qualification standard, guaranteeing its suitability and reliability for automotive environments. This certification is a prerequisite for most automotive designs.
• Tolerance (±10%): This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose and many automotive applications, indicating a good balance between precision and cost-effectiveness.
• L x W Size (1.6mm x 0.8mm [EIA 0603]): This denotes the physical dimensions of the capacitor. The 1.6mm length and 0.8mm width correspond to the industry-standard EIA 0603 package size, which is a very common and compact footprint, ideal for miniaturized electronic assemblies.
• Capacitance (1nF): The nominal capacitance value is 1 nanofarad (1 x 10^-9 Farads). This value is suitable for a wide range of applications, including signal coupling, decoupling, and high-frequency filtering.
• T(Max.) / mm (0.9): This indicates the maximum thickness of the component, which is 0.9mm. This dimension is important for mechanical design and ensuring proper fit within constrained spaces on a printed circuit board (PCB).
• Temp. Chara. (X8R): X8R is a specific temperature characteristic code defined by EIA. It signifies that the capacitance change over the operating temperature range of -55°C to +150°C is within ±15%, making it highly stable across a very wide temperature spectrum, which is essential for automotive and industrial applications.
• Component Type (Ceramic Capacitor (MLCC)): Confirms its fundamental type as a Multilayer Ceramic Capacitor, known for its high-frequency performance, low equivalent series resistance (ESR), and compact size.
• Product Status (Production): Indicates that the component is actively being manufactured and is readily available for new designs and mass production, ensuring long-term supply stability.
• Rated Voltage [DC] / V (100): This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 100V rating provides ample headroom for many automotive and industrial control circuits.
• Cap.Change or Temp.Coef. (±15%): This reiterates the capacitance change over the specified operating temperature range, directly correlating with the X8R temperature characteristic. It guarantees stable performance even under significant temperature fluctuations.
• Operating Temp. Range / °C (-55 to 150): This specifies the full range of ambient temperatures over which the capacitor is designed to operate reliably, from extreme cold to very high heat. This wide range is a hallmark of automotive-grade components.

Features and Benefits
